feat(mat): wire real ESP32/UDP/PCAP CSI ingest; honest typed errors for gated adapters (ADR-158 §3)
hardware_adapter read_esp32_csi/read_udp_csi/read_pcap_csi returned 'not yet implemented'. Wired them to the real CsiParser/PcapCsiReader that already live in csi_receiver: - UDP: bind + recv + parse (auto-detect) -> CsiReadings. End-to-end test sends a real JSON datagram on the wire and parses it. - PCAP: load + read_next + parse. End-to-end test writes a real little-endian .pcap with one record and reads it back. - ESP32: parse CSI_DATA CSV via the real parser; live serial byte I/O behind an optional feature (native serialport gated off the default/appliance build) — without it, live reads return a typed UnsupportedAdapter while the byte parser still works (tested). Intel5300/Atheros/PicoScenes now return typed HardwareUnavailable/UnsupportedAdapter (no device/driver/validatable-format here) instead of fake CSI — added AdapterError::HardwareUnavailable and ::UnsupportedAdapter. Test asserts the gated adapters error honestly. Co-Authored-By: claude-flow <ruv@ruv.net>
